Theoretically, more rifling grooves will produce better accuracy. But one rapidly reaches a point of diminishing returns.

I speculate that a 6-groove barrel will be quicker and cheaper to manufacture. 6 grooves requires the removal of less metal from the bore, but, of course, produces a bit higher back pressure during firing.

I am unaware of SA making any 6-groove barrels.

Hope this helps.
